- Provide common kallsyms wrapper API
  With bsc#1103203, the need for disambiguating between a multiply
  defined symbol arose. This is something the kallsyms_lookup_name() based
  code snippet we used to copy&paste to every individual CVE fix can't
  Implement a proper wrapper API for doing the kallsyms lookups.

- provide KLP_SHADOW_ID() helper macro
  In analogy to the KGR_SHADOW_ID() macro, introduce KLP_SHADOW_ID() for
  the construction of unique shadow variable id's.

- scripts/ implement conditional inclusion
  Currently, subpatches provide a patched_funcs.csv file describing what
  needs to be patched. inspects those to assemble one
  global klp_patch structure.
  The current format for these patched_funcs.csv's is
  obj old_func(,sympos) newfun
  However, sometimes subpatches depend on some kernel configuration values
  like CONFIG_X86_64 and functions shall get patched only if the target
  kernel configuration matches.
  Extends the patched_funcs.csv format to
  obj old_func(,sympos) newfun (cpp condition)
  where everything coming after 'newfun' is taken to be a CPP condition to be
  used for conditional inclusion. In case there's no condition specified,
  assign that entry the same semantics as if a '1' had been given.
  Make guard the corresponding klp_func entries with #if
  Furthermore, let it guard the enclosing klp_object instances by or'ing
  together all its klp_funcs' conditions.
  For the sake of better readability, omit redundant #if pragmas as well as
  condition clauses. In particular,
- if a function entry hasn't got any condition explicitly specified,
  there won't be any #if pragma, neither at the klp_func nor at the
  klp_object level,
- if multiple function entries for an object are protected by the same
  condition, it'll be or'ed in at the klp_object level only once,
- if all of an object's functions share the same condition, no #if pragmas
  will be emitted at the klp_func level because they would only duplicate
  what's already there for the enclosing object and
- multiple subsequent function entries sharing the same condition get

- scripts/ allow spaces as patched_funcs.csv separators
  Currently there's one single cut(1) usage which requires that (single) tabs
  are used as field separators for the patched_funcs.csv.
  As the rest of the code can deal with sequences of any whitespace already,
  this imposes an unnecessary restriction on the format.
  Substitute that cut(1) usage by a sed(1) invocation as appropriate.

- livepatch_main.c: klp_patch_init(): fix error handling
  In case either of the invocations of klp_register_patch() or
  klp_enable_patch() fails, anything which has been setup by the prior
  per-(sub-)patch initialiation code, i.e. the expansion of
  @@KLP_PATCHES_INIT_CALLS@@, won't get undone.
  Fix this.

  and adjust scripts/ accordingly.

- scripts/ generate klp_object array
  The KLP API doesn't take a flat list of to be patched functions
  like KGraft did, but introduces an intermediate layer: struct
  Each klp_patch instance is supposed to reference an array of
  klp_object's which in turn provide an array of klp_func's each.
  To facilitate merging, we want to generate this list of klp_object's
  automatically, exactly like we did for the flat function list with KGraft.
  For each klp_patch instance, there must be at most one klp_object entry
  referring to the same object.
  Hence care must be taken not to add an entry for the same object twice
  in case two different (sub-)patches both patch some functions therein.
  Require from each (sub-)patch to provide the list of to be patched
  symbols in a file named SUBPATCH/patched_funcs.csv with each line
  conforming to the
  obj old_func(,sympos) new_func
  Make scripts/ generate an klp_object array initializer based on
  this and let it expand the @@KLP_PATCHES_OBJS@@ tag within livepatch_main.c
  Do not replace the now obsolete @@KLP_PATCHES_FUNCS@@ anymore.
  Add and remove the @@KLP_PATCHES_OBJS@@ and @@KLP_PATCHES_FUNCS@@
  markers to and from livepatch_main.c respectively.

- shadow variables: add KGR_SHADOW_ID helper
  As shadow variables are supposed to be shared among different KGraft
  modules their id's must be compile time constants.
  Introduce the KGR_SHADOW_ID helper macro for generating them in a uniform
  manner based on the bsc# number and a local id.
- commit 237c8f3

Thu Oct  5 12:12:28 CEST 2017 -

- shadow variables: share shadow data among KGraft modules
  As it stands, each KGraft module maintains its own set of shadow variable
  management structures and thus, shadow variables are not sharable between
  livepatch modules.
  This behaviour is different from the upstream implementation and, as
  pointed out by Miroslav Benes, it also opens up an opportunity for a small
  window where the system might become vulnerable again during transition as
  we stack new livepatches on top.
  Let all KGraft patches share the shadow data.
  Sharing is implemented by moving the management structures from a KGraft
  module's .data to dynamically allocated memory. Each KGraft module will
  have specifically named pointers, 'kgr_shadow_hash12' and
  'kgr_shadow_lock12', referencing them.
  Upon initialization, a KGraft module will discover already existing such
  shadow data by kallsyms-searching all loaded modules for these pointer
  symbols. If none is found, a new instance is allocated. The newly
  introduced kgr_shadow_init() implementing this is idempotent and can thus
  be called from the bsc# subpatches' initializers if needed.
  Upon KGraft module removal, the new kgr_shadow_cleanup() will conduct
  another kallsyms search and deallocate the shadow data in case there are
  no more users. kgr_shadow_cleanup() is also idempotent.
  Initialization and teardown of the common shadow data is serialized with
  the module_mutex which has to be taken for the kallsyms search anyway.

- shadow variables: drop EXPORT_SYMBOL()s
  The shadow variable API will only ever get used by the KGraft module itself

- shadow variables: introduce upstream patch
  Joe Lawrence posted the sixth version of his shadow variable patch [1]
  implementing the association of additional out-of-band data members to
  existing structure instances from livepatches.
  Jiri Kosina has applied this to his
  git:// for-4.15/shadow-variables
  tree and thus, it's queued up and close to getting merged.
  The plan is to eventually backport this shadow variable support to SLE
  kernels, but we also want to have it usable from KGraft modules by now.
  Port the implementation to the kraft-patches module.

- scripts/ register subpatch sources in rpm spec
  In order to reduce the manual merging work upon addition of new
  (sub)patches, commit 4e8dc885be22 ("scripts: create kgr_patch_main.c
  dynamically") introduced the helper. It discovers
  those and tweaks the main entry point, kgr_patch_main.c, as needed.
  However, a remaining manual merging task is to list a (sub)patch's source
  archive in rpm/kgraft-patch.spec and to %setup it.
  Make scripts/ do this.
  placeholders in rpm/kgraft-patch.spec
- and make scripts/ expand those within a spec file
  to be given as an additional command line argument.
  Finally, adjust scripts/ accordingly.

- scripts/ don't add ','s to @@KGR_PATCHES_FUNCS@@ expands kgr_patch_main.c's @@KGR_PATCHES_FUNCS@@
  placeholder by concatenating all available patches' KGR_PATCH_<XY>_FUNCS
  together, separating them by commas.
  The KGR_PATCH_<XY>_FUNCS are CPP macros supposed to be provided by each
  patch. If one of these happens to be empty, the preprocessed expansion
  will contain two consecutive commas which gcc doesn't like in array
  Do not add any commas to the @@KGR_PATCHES_FUNCS@@ expansion but require
  the individual KGR_PATCH_<XY>_FUNCS macros to already contain trailing
  ones as needed.

- scripts: create kgr_patch_main.c dynamically
  The kgraft-patches repository has got many branches, each corresponding
  to a supported codestream. Each of those carries a potentially different
  set of live (sub)patches which are controlled through the entry points in
  kgr_patch_main.c. According to Miroslav, merging of a new (sub)patch
  based on the pristine master is a pita due to conflicts.
  Since all (sub)patches stick to certain conventions already, the required
  modifications of the merging-hotspot kgr_patch_main.c are quite mechanic.
  Let a script do the work.
- insert some special @@-embraced placeholders at the few places depending
  on the actual set of (sub)patches,
- let discover the available (sub)patches by searching
  for directories
- and let replace those placeholders in
  Finally, add a invocation to
  This procedure requires that a SUBPATCH located in directory SUBPATCH/
  adheres to the following conventions:
- It must provide a provide a SUBPATCH/kgr_patch_SUBPATCH.h header.
- This header must provide declarations for kgr_patch_SUBPATCH_init()
  and kgr_patch_SUBPATCH_cleanup().
- This header must also #define a KGR_PATCH_SUBPATCH_FUNCS macro.
  It should expand to a comma separated list of KGR_PATCH*() entries,
  each corresponding to a function the subpatch wants to replace.

- Set immediate flag to false
  Using immediate set to true can lead to BUGs and oopses when
  downgrading, reverting or applying replace_all patches. There is no way
  how to find out if there is a process in the old code which is being
  removed. The module would be put, removed and the process will crash.
  The consistency model guarantees that there is no one in the old code
  when the finalization ends. Thus use it for all case to be safe.
